What Is the Lymph Trunk?

Lymph (Latin: lymph) is also called lymph fluid. It is a colorless and transparent liquid in humans and animals. It contains lymphocytes and is formed by tissue fluid infiltrating into lymphatic vessels. Lymphatic vessels are tubes similar in structure to veins and are distributed throughout the body. The lymph circulates in the lymphatic vessels, and finally flows into the vein, and part of the tissue fluid flows into the blood back and forth. Lymphs are found in all parts of the body and play a vital role in the body's immune system.

The lymphatic system is an integral part of the vasculature.

Lymphoid tissue

"Toxins in the body are excreted in sweat, vomit, and the next three ways, namely sweating, vomiting, and urination.

1. New lymphatics are constantly produced.

2. Smooth muscle contraction on the lymphatic wall.

3 Vascular pulsations around the lymphatic vessels.

4 Negative chest pressure.

5. The muscles around the lymph contract.

6. Homeopathic opening and closing of lymphatic valves.

lymph node enlargement

Lymph nodes increase in size due to internal cell proliferation or tumor cell infiltration. Common clinical signs. It can be found by touching the submandibular, neck, supraclavicular fossa, axillary and groin, but the enlarged lymph nodes in the body such as hilum, mediastinum, retroperitoneum and mesentery can only be found by X-ray, CT and B ultrasound. .

There are three common conditions for lymphadenopathy:

Benign enlargement. Including swelling caused by various infections, connective tissue diseases and allergies. The clinical process is usually benign. With the removal of the cause, it can be completely recovered within a certain period of time.

Malignant swelling. Includes lymph node metastases such as lymphoma, lymphocytic leukemia, and malignant histiocytosis, and lymph node metastases such as lung cancer, gastric cancer, and breast cancer. The clinical manifestations are malignant and the lymph nodes are persistently enlarged. If they are not actively treated, they will often progress to death.

Swelling between benign and malignant. Such as angiogenic immune cell lymphadenopathy and vascular follicular lymphadenopathy. It is often benign at first and can become malignant and lethal. Therefore, after the determination of lymphadenopathy, the key is to determine the cause and nature. Local enlargement with obvious pain often indicates infection; progressive painless enlargement often indicates malignant tumor disease. Bone marrow aspiration, especially lymph node biopsy, can help confirm the diagnosis.

The treatment of lymphadenopathy is based on the disease. For example, streptomycin and remifen can be used for lymphatic tuberculosis. If it is malignant lymphoma, it should be combined with chemotherapy. If it is advanced metastasis, the prognosis is very poor.
